Morphology
The meaning 'an electromagnetic wave used for radio communication' is directly compositional from 'radio' (the broadcasting/communication medium using electromagnetic signals) + 'wave' (a propagating disturbance). This nominal compound follows common compounding patterns found across languages, so a B1 learner who knows both constituents can reliably infer the MWE meaning.
Etymology
Radio wave comes from the simple image of a radio sending invisible ripples like a wave through the air that move away from the sender. Those invisible ripples 'carry' voice and music, so the name means 'waves that carry signals'.
